Minerals are found in varied forms in nature, ranging from the hardest diamond to the softest talc. Classify minerals - shortcut Based on the chemical and physical properties, minerals are broadly classified as metallic and non-metallic.

Properties of soil. Soil is the thin layer of matter that covers the earths surface, made up of organic matter, minerals and weathered rocks. There are a number of factors that affect the physical and chemical properties of soil in a landform. The primary factors are parent rock and climate in the area. The parent

Naturally Occurring - Minerals are found on Earth and not nan-made. Inorganic - Minerals do not consist of living matter. Solid - Minerals have a definite shape and volume. Crystal Structure - Particles inside minerals form a crystal pattern. Definite Chemical Composition - Minerals are made up of Periodic Table elements- not limited to compounds

Properties of Graphite Graphite is an allotrope of carbon which is used for making moderator rods in nuclear power plants. Its properties are as follows: A greyish black, opaque substance. Lighter than diamond, smooth and slippery to touch. A good conductor of electricity( Due to the presence of free electrons) and good conductor of heat.

Metallic Minerals is composed of metals in their original form, whereas no metals are found in non-metallic minerals. Metallic minerals are good conductors of heat and electricity. E.g iron, copper, bauxite, etc. Non metallic minerals are good insulators and include coal, dolomite, phosphate, salt, granite, etc.

Q. It has excellent dielectric strength, low power loss factor, insulating properties and resistance to high voltage. It is one of the most indispensable minerals used in the electric and electronic industries. Its most common minerals are lepidolite, biotite, phlogopite and muscovite.

Properties of Pumice. It mainly consists of highly microvesicular glass pyroclastic with very thin, translucent bubble walls of extrusive igneous rock. Also, it is usually pale in color and ranges from white, cream, blue or grey, to green-brown or black. It forms when volcanic gases come out from viscous magma.

Which are the important minerals available in Karnataka? View Solution. Q3.

The process of procuring metals from ores is called metallurgy and these naturally occurring compounds of metals are known as minerals. Metals are usually extracted from the earth by mining. Ores. All ores are minerals, but not all minerals are ores. Ores are those minerals which contain metals. The picture shown above is a gold-bearing ore.
